[PlanetCCRMA] Lost sound on FC3

[Ron Pepper]

I'm new to Linux and have a dell P4 desktop machine which is set up
to dual boot linux and xp. The sound card is a built in Soundblaster
Live! and isn't recognized properly by FC3 on install. After checking
the forums, I found that this is a known issue with Dell Dimension
4550. Linux sees the soundcard chip as emu10k1, but it is actually
somewhat different. The ALSA site shows my chip to be emu10k1x and
subsequent checks confirmed this. 

So I followed the directions on the ALSA site to configure and
install the new module. Since I didn't really know what I was doing,
I just followed what was written and asked for help from the ALSA
list when I got stuck. After much struggle, I finally got the sound
to work. System sounds worked and ogg files I downloaded to the hd
worked. I could play them from sites as streaming audio as well. I
couldn't get Gnome player to play inserted CD's, however. I would get
a "disk error" message from the player. I thought this might be a
permissions issue as I got error messages when I tried from the ALSA
site:

Permissions were never set properly, according to ALSA: 
The snddevices script sets the permissions for the devices it creates
to root. You should
        "chmod a+rw /dev/dsp /dev/mixer /dev/sequencer /dev/midi" 

When I tried this, I got:
>[root@localhost alsa-driver-1.0.8]# chmod a+rw /dev/dsp /dev/mixer
>/dev/sequencer /dev/midi
>chmod: cannot access `/dev/dsp': No such file or directory
>chmod: cannot access `/dev/mixer': No such file or directory
>chmod: cannot access `/dev/sequencer': No such file or directory
>chmod: cannot access `/dev/midi': No such file or directory

>From the list, I was advised:

"If you make sure your system has a group named "audio", then the
snddevices script will create devices with a group attribute of
"audio"

In /dev/snd for example:
crw-rw----    1 root     audio    116,  24 Feb 20 11:40 pcmC0D0c

Then all you have to do is ensure that your users are members of a
group
named "audio".

on my system:
cat /etc/group | grep audio"

Unfortunately, I didn't really understand what I was doing and now
have lost all sound! I'm a newbie and don't know how to troubleshoot
this. Help would be appreciated!

Thanks, Ron
